ghee-grose.. ha.. was not replying to you. I was telling widowmaker.. a lot of people on the U Can Do 60 forum say the 16x4W prop has a long spool up time. Just was not the case with the ys 1.1 IMO.

I think the ys 1.1 would be slightly overpowering the twist.. ha.. That would be CRAZY.

I am thinking ys 63S... maybe saito 72 or 91S.. but... don't want to deal with installing a regulator and I like the built in pump.
